.IMPROVEMENT IN PUMPS..

TO ALL PERSONS 'TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, NATHAN Paiemdr., of Danvers, in the county of Essex, and State of Massachusetts, have invented a. new and useful Improvement in Force-Pumps, and for washing windows, watering gardens, etc.; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of whicl1-- Figure is a side elevation, Y

Figure 2 is a 'vertical and longitudinal section, and

Figure 3 a transverse section ofa pump provided with my invention.

In this pump the plunger and its handle constitute the eduction-tube or apart thereof, a short hose, provided with a nozzlc'orjct-tubc of any desirable kind, being applied to the discharging lend of the handle.

The main purpose of the improvement made by me in this kind of pump is to conduct back into the vessel or bucket, into which the pump may be placed for the purpose of discharging water therefrom, any waste water whichma-y flow up between the plunger and the pump-barrel. The secondary object of my invention is to make a. l`very strong and light pump-barrel.

. In the-drawings, A denotes the pump-barrel, which may be supposed to have a cylindrical bore, and to be *constructed of thin sheets of metal, as tinned iron, for instance. B is the plunger, which is a' tube, which is furnished with an annular cap or shoulder, a, to rest on the upper end of the barrel when the plunger is in its lowest position. A valve, b, to open upward, is placed at the lower par-t of the barrel. The plunger communicates dii'cctlywith and opens into its handle C, which is also tubular and open at its smaller end, it beingucloscd at its larger extremity. The pipcB', which leads fromvthc plunger B into handle C, is'extcnded down within the plunger, for the purpose of making a chamber in the upper part of the plunger, in which the air will be compressed by the water, when the plunger is being forced downward, such compression of the air serying to aid in` p producing a steady discharge through the handle C. :There is also ,a valve, c,`in the plunger, and at the lower ondof the plunger there is a ilexiblc or elastic annulus, d, of vulcanized India rubber or leather, which is ailxed to the `plunger, and otherwise arranged as shown. 'lhe pump-barrel is surrounded by'a corrugated case, E, which forms a. series of channels or conduits, ff, extending down from the top to or nearly to the bottomv of the barrel, each of such channels being closed at its upper and open at its lower end. There is an opening, e, leading from the upper part of the barrel into cach, or some one or more of such conduitsf. Any water or liquid which maybe driven or drawn up -into the space between the plunger and the barrel will be forced through the opening vor openings e, and will run down the channel or channelsf and be discharged into the bucket or vessel from which the water may vbeextracted. When theplungcr is driven downward in the barrel, the resistance of the fluid therein will expand the elastic or ilexile annulus and force it closely against the barrel, the water passing up within the plunger. 'lhe barrel, at its lower end, may be provided with a bell or conical mouth-piece, r, and

such barrel may also have a foot-rest, 1', formed of` wire, and inserted in sockets k t,fi,\cd to the side of the frame.

What I claim as my invention` ist The combination and arrangement of the corrugated covering E, the barrel A, one or more openings e, and the tubular plunger B, opening into the handle C, through the tube Il. all substantially as described.
